Mount Your PL-Mount Lens to Your BMPCC4K

The Metabones PL to BMPCC4K T CINE Speed Booster ULTRA 0.71x (Black Matt) lets you mount a PL-mount lens onto your Blackmagic Design Pocket Cinema Camera 4K MFT-mount camera. The adapter's optics help to widen the connected lens's angle of view, while also increasing the camera's aperture range by 1-stop.

The BMPCC4K Speed Booster ULTRA 0.71x and XL 0.64x are similar to the standard M43 Speed Booster adapters but the optics have been re-designed to optimize for the filter stack thickness of 2.4mm found in Blackmagic cameras rather than the 4mm of a standard Micro Four Thirds.

he BMPCC4K Speed Booster ULTRA 0.71x reduces the crop factor of the BMPCC 4K camera from 2.02x to 1.43x

Metabones PL-mount to BMPCC4K Speed Booster adapters is designed exclusively for Blackmagic Design Pocket Cinema Camera 4K (BMPCC4K). They cannot be attached to any other M43 cameras such as JVC, Olympus or Panasonic cameras.

Metabones PL T CINE Speed Booster adapters are designed exclusively for the Zeiss CP.2, CZ.2, and CP.3 lenses. Important Notes: Do not attempt to mount the lenses not under the Lens Comparability List to the adapter - physical damage may occur.

  • Allows a PL-mount lens to be used with a Blackmagic Design Pocket Cinema Camera 4K MFT-mount camera
  • Maximizes apparent angle of view of combined camera and lens
  • Provides a 1-stop increase for the camera over the lens's aperture range
  • 6 lens elements in 4 groups for optical clarity as well as colour fidelity
  • Internal coating minimizes reflections within the adapter barrel
  • Detachable, Arca-Swiss compatible tripod foot with 1/4"-20 threads matches the BMPCC 4K camera height
  • Positive-lock PL lens mount.


Optimized for the filter stack thickness of 2.4mm found in Blackmagic cameras rather than the 4mm of a standard Micro Four Thirds.

  • PL-mount lens to Blackmagic Design cameras with M43 mount, specific for BMPCC4K.
  • Increase maximum aperture by 1 stop. (with a maximum output aperture of f/0.9).
  • Increase MTF.
  • Makes the lens 0.71x wider.
  • Patented 6-element/4-group optical design incorporating ultra-high index tantalum-based optical glass by Caldwell Photographic in the USA (patent granted).

If a lens intended for 35mm film or similarly sized full-frame camera sensors is connected to a camera with a Micro Four Thirds-sized sensor, it would project an image larger than the Micro Four Thirds sensor was built to accept. Able to capture only the centre portion of the projected image, the effective angle of view of the lens would be narrowed, creating an in-camera "crop factor." The T Speed Booster ULTRA 0.71x adapter condenses the light from a lens designed for 35mm film or "full-frame" camera sensors and projects it onto a Micro Four Thirds sensor. This allows the Blackmagic Pocket Cinema Camera 4K with a Micro Four Thirds sensor to utilize more of the light gathered by a connected lens, which effectively reduces the crop factor while making available to the sensor an additional 1-stop of light for each of the lens's f/stop settings.

Quality Construction

This adapter is constructed from aluminium for durability while minimizing weight and its mounting rings are made with brass to further prevent wear and tear a detachable tripod foot is included and features 1/4"-20 threads as well as compatibility with Arca-Swiss tripod heads.

  • Internal flocking to reduce internal reflection.
  • Rubber gasket protects M43 mount connection from dust and moisture.
  • Aluminium alloy and brass construction with chromium plating.
  • Satin surface finish.
  • Detachable tripod foot compatible with Arca Swiss Style ball head or attach to quick release plate by a 1/4"-20 screw.
  • The tripod foot is tailor-made to match the exact height of the BMPCC4K camera body.
  • Positive-lock PL lens mount.
